    摘要: The arrangement can transfer with respect to a beam, elastic threads having a predetermined initial extension. The arrangement has a first device for imparting a first thread speed to the threads being transferred. Also included is a controller and at least one tension roller, the latter rotatably mounted between the beam and the first device. The roller can impart a second thread speed to the threads and can stretch them. The threads at the beam are transferred at a third thread speed. Among the first, second and third thread speeds the two furthest upstream have an adjustable speed ratio. The controller can measure the tension of the threads traveling to the tension roller. This controller is operable to alter the speed ratio in response to the tension of the threads, to hold this tension at a predetermined magnitude.

    摘要: A blocking device, preferably in the form of a baffle plate is provided behind the rollers of a thread tightener in a bobbin creel which can be pressed against one another, namely behind the roller pair in the direction of the through-passage. In case of a thread break, the baffle plate prevents the loose thread end from falling out of the roller tightener. Preferably, the baffle plate is latched onto a thread hoop and rotatably journalled, so that it can be swung from an operations position into a neutral position.

    摘要: A beaming machine (beamer) suitable to run any common width beam for Raschel-type knitting machines, having three beams or heads with individual traverse settings so that different yarn end counts can be simultaneously wound on each beam. Uniform yarn tension is obtained at each beam by a series of two rollers positioned between the beam and the yarn creel over which each yarn end must pass. An evenly wound beam is thereby obtained for each of the three beams. Doffing time is minimized by the tensioning rollers in conjunction with pigtail-shaped yarn end guides mounted on one of a plurality of reeds adapted for the various end counts capable of being wound by the machine. Yarn breakage is detected by the breaking of a light beam in conjunction with an air sheet generated from an air slit for each beam. An air sheet is directed toward each yarn sheet so as to blow any broken yarn end across the light beam and thereby electronically initiate a shut-down of the beamer.
